Hi Gavin Anderson,
Firstly with regards to the valuation of the business this is more appropriate to my colleagues at Companies House.
If you are going to set up a company, you will need to go through incorporation.
Please see:

With regards intellectual property, I would refer you to:
Intellectual property and your work
And finally with regards incorporation relief I would refer you to:
Incorporation Relief
If this information does not answer all your queries, I would suggest that you contact a professional accountant for further advice.
Thank you.
